Suppresses pathogenic E. coli O157, which causes food poisoning

It has been proved that the active elements produced by Streamer technology decompose and neutralize O157 , which causes food poisoning. Furthermore, this time, it has been proved that the suppression effect is increased 18 times by operating two Streamer units.

* The results are obtained from demonstration of solely the Daikin Streamer discharge device in an experimental condition.

Demonstration of the suppression effect against O157

Operation of one Streamer unit

Streamer - surpression effect against O157 with one streamer unit

Operation of two Streamer units

Streamer - surpression effect against O157 with two streamer units

Testing organization

Japan Food Research Laboratories

Test method

By irradiating the O157 with Streamer for 1, 2, 3, 4, 8 hours and inoculating the cultured cells, we observed the residual state of the O157 by the difference in the Streamer irradiation time.

Streamer -  comparison surpression effect against O157 with one and two streamer units

The survival rate of O157 after 2 hours of the Streamer irradiation was 0.1% for operation of two units compared to 1.8% for one unit operation, confirming that the suppression was 18 times more effective. In addition, after 3 hours, it was confirmed that the suppression effect was 99.9% both with the one unit operation as well as with the two unit operation.

* The results are obtained from demonstration of solely the Daikin Streamer discharge device in an experimental condition.

O157 with strong toxin and infectivity

O157 produces a strong toxin called Verotoxin, which causes abdominal pain, hemorrhagic diarrhea, and vomiting. It is one of the most dangerous bacteria that can cause severe symptoms and deaths when infected in infants and the elderly. In addition, infectiousness is strong. General food poisoning only develops when "about 1 million" of bacteria invade, whereas O157 develops food poisoning even with a small number of "about 100" bacteria.
